应用级权重规则不生效

- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.

### Environment

* Dubbo version: 3.0.10
* Operating System version: 10.15.7
* Java version: 1.8.0_231
* Dubbo-admin version: develop(60c146fedcdf0291ad44959f5d6fccbbd9e94806)

### Steps to reproduce this issue

1. 本地启动一个服务，并设置application=dynamic-router-demo-server_local
2. 在dubbo-admin中设置应用级的权重规则

3. 权重没有调整，还是维持之前的权重状态，且dubbo-admin权重应用级和接口级别权重不一致（之前设置接口级权重规则成功）


5. 经过debug发现权重没有调整

Pls. provide [GitHub address] to reproduce this issue.
